Adobe's DNG converter is dead handy, but I'm sure they'll update it to ARM, so that's not a huge problem. I would miss it if they gave up on it. Furthermore I still use Photoshop CS4, because in 2020 it has a sweet spot of performance and features. CS4's version of Camera Raw added a handy graduated filter that wasn't in CS2, for example. The DNG converter is useful because the last version of Camera Raw for CS4 only supports cameras up until around 2012 or so.
Obviously Adobe would love it if I stopped using CS4, but it works and it's powerful enough for my needs. The image processor and action scripting has a neat mixture of simplicity and power. A while back I wrote a blog post about
Microsoft Flight Simulator 2020; for whatever reason the game doesn't have a screenshot key, so the only way to take screenshots of the game is to grab the entire workspace, which includes the contents of my second monitor. It would be personally embarrassing if the world discovered that I have hundreds of tabs of top glamour legend Ana Foxxx open in the background while I'm pretending to fly a plane. That's just a hypothetical example.
It was the work of a few moments to generate an action that took a directory of images that looked like this:
Into something that looked like this:
With more sensible names than "screenshot (213)". I don't like filenames that have spaces or punctuation marks. It's bound to be a problem somewhere down the line. MS Flight Simulator 2020 looks fantastic, although obviously it's not available for MacOS, and probably never will be.
The oldest Windows application I still occasionally use is CoolEdit, from 1996 - it still works in Windows 10. I find the interface easier to use than Audacity, but I imagine it would run fine under emulation given that it was designed for machines that have less processing power than a modern smartphone battery.
